Subtracting Mixed Numbers With Like Denominators Worksheet
Table of Contents :
Subtracting mixed numbers with like denominators can seem daunting at first, but with the right approach and practice, it becomes a manageable task! In this article, we will break down the steps to subtract mixed numbers, illustrate these steps with examples, and provide a worksheet to help you master this skill. Let’s dive in! 📚
Understanding Mixed Numbers
A mixed number is a combination of a whole number and a fraction. For example, ( 2 \frac{1}{3} ) is a mixed number, where 2 is the whole number and ( \frac{1}{3} ) is the fraction.
Key Terms
- Whole Number: The integer part of the mixed number.
- Fraction: The part that represents a portion of a whole.
- Like Denominators: Fractions that have the same denominator, making it easier to perform operations.
Steps to Subtract Mixed Numbers with Like Denominators
When subtracting mixed numbers, especially those with like denominators, follow these straightforward steps:
- Separate the Whole Numbers and Fractions: Break down the mixed numbers into whole numbers and fractions.
- Subtract the Whole Numbers: Subtract the whole number parts from each other.
- Subtract the Fractions: With like denominators, simply subtract the numerators while keeping the denominator the same.
- Combine the Results: Put together the whole number and the fraction results. If necessary, simplify the fraction or convert it back into a mixed number.
Example
Let’s go through an example to make this clear:
Problem: Subtract ( 4 \frac{3}{8} - 2 \frac{1}{8} )
-
Separate the Whole Numbers and Fractions:
- Whole numbers: 4 and 2
- Fractions: ( \frac{3}{8} ) and ( \frac{1}{8} )
-
Subtract the Whole Numbers:
- ( 4 - 2 = 2 )
-
Subtract the Fractions:
- ( \frac{3}{8} - \frac{1}{8} = \frac{3-1}{8} = \frac{2}{8} )
-
Combine the Results:
- Whole number: 2
- Fraction: ( \frac{2}{8} ) simplifies to ( \frac{1}{4} )
Final answer: ( 2 \frac{1}{4} )
Practice Worksheet
Now, let’s create a practice worksheet to solidify your understanding! Below, you'll find a table with mixed number subtraction problems you can try:
<table> <tr> <th>Problem</th> <th>Answer</th> </tr> <tr> <td>1. ( 5 \frac{2}{5} - 3 \frac{1}{5} )</td> <td></td> </tr> <tr> <td>2. ( 6 \frac{4}{9} - 2 \frac{2}{9} )</td> <td></td> </tr> <tr> <td>3. ( 3 \frac{3}{10} - 1 \frac{7}{10} )</td> <td></td> </tr> <tr> <td>4. ( 4 \frac{5}{12} - 2 \frac{1}{12} )</td> <td></td> </tr> <tr> <td>5. ( 7 \frac{1}{6} - 3 \frac{2}{6} )</td> <td></td> </tr> </table>
Important Note
